Apple tree named ‘Lynn’

ABSTRACT

A new and distinct variety of apple tree, characterized by an unusually shiny yellow ground color and a glossy pink-red overcolor, maturing about 5 days later than ‘Red Delicious’, with crisp, juicy flesh capable of both dessert and culinary use.

Latin name of the genus and species of the plant claimed: Malus pumila, Mill.

Variety denomination: ‘LYNN’.

BACKGROUND OF THE INVENTION

Disclosed is a new and distinct variety of apple (Malus pumila, Mill) that was discovered in a cultivated area of the back yard of my residence off Washington State Highway 28, Rock Island, Wash. The seedling apparently germinated in about 1990 and was basically ignored until it fruited in 1999. I noticed the color and quality of this initial fruit. In the Spring of 2000, I grafted budwood from the seedling onto about 100 ‘Jonagold’ (unpatented) trees growing on Malling 7 (unpatented) rootstock. This grafting took place in Rock Island, Wash. Approximately 10 of these grafts produced fruit in 2001. The fruit from these grafts and other characteristics of these grafts were identical to the fruit and other characteristics of the original seeding, thus confirming the stability of this new variety. I decided to call my new variety ‘LYNN’.

BRIEF SUMMARY OF THE INVENTION

My new variety is a seedling apple tree with a distinct pink-red blush over about 20 to 80 percent of the fruit surface, which has a glossy yellow ground color. In addition, the fruit size typically is large, the shape conic, and the flesh crisp, juicy, and sweet-tart in flavor. These characteristics make it a clearly distinct new variety.

This apple of my new variety is very distinctive, not sharing a number of external or internal characteristics with any other variety. The apple of my new variety has the pink on yellow coloring similar to ‘Winter Banana’ (not patented), but is much different in shape. ‘Winter Banana’ is more round in shape with a very shallow basin. ‘Winter Banana’ apple ripens in mid-late October and ‘Lynn’ ripens in mid-September.

‘Cripps Pink’ (U.S. Plant Pat. No. 7,880) has a similar pinkish coloring but matures in late October to November and is much more acidic at harvest time.

‘Blushing Golden’ (U.S. Plant Pat No. 2,835) has a pinkish-red blush but resembles ‘Golden Delicious’ in shape and internal quality. The ground color of ‘Blushing Golden’ is deep yellow and dull in luster, while ‘Lynn’ is very glossy.

‘Criterion’ (U.S. Plant Pat. No. 3,505) is somewhat similar in color and maturity but very different in shape. ‘Criterion’ is distinctly conical and ribbed while ‘Lynn’ is more round conical with less prominent lobes at the calyx end. ‘Criterion’ is no longer grown commercially.

Asexual reproduction by grafting at Rock Island, Wash., as set forth above, has shown that the characteristics of my new variety are established, firmly fixed, and are transmitted through succeeding asexual propagation.

Certain characteristics of this variety, such as growth and color, may change with changing environmental conditions (e.g., photoperiod, temperature, moisture, soil conditions, nutrient availability, or other factors). Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Color designations (hue/value/chroma) are made with reference to the Munsell Book of Color, Kollmorgen Instruments Corp., 405 Little Britain Road, New Windsor, N.Y. 12553.
